Owner-builder application

Becoming an owner-builder

To become an owner-builder, you must obtain owner-builder approval from the Building Commission. To do this you will need to complete and submit an owner-builder application form and pay an application fee.

When applying to become an owner-builder, the Building Services Board requires you to demonstrate that you have sufficient knowledge of your duties and responsibilities before giving approval.

The approval process timeframe

90 per cent of owner-builder approval applications are determined within 11 weeks. The Building Commission will contact you if any further information is required to process your application. You will be notified as soon as a decision regarding your application has been made.

Restrictions on building as an owner-builder

Once your owner-builder approval has been issued, you must apply for a building permit from your local permit authority within six months. If you do not, your owner-builder approval will expire. 

Owner-builders can only be issued with a building permit once every six years. If you have been issued with a building permit by the local government within the last six years, it is an offence to declare that you have not.

The Board has discretion to vary this restriction and grant an exemption from the six year restriction. Exemption is granted only in circumstances where significant hardship would be suffered if the request was refused. To apply for an exemption, you must submit a written application to the Board.

Application to the Board for an exemption

For approval to obtain another building permit without the requirement for home indemnity insurance, you must lodge a statutory declaration and satisfy the Board that:

  • a change of circumstances has occurred; and
  • the applicant would suffer hardship if the application was refused.
